. SPECIFICATION forming part of Letters Patent No.` 245,161, dated'August 2, 1881.

` Application filed March 24, 1881). (No model.)

To all whom' it may concern Be it known that 1, JOHN E. ennnmcma citizen of the United States, residing atJe'rof New J ersey,haveinventednew and useful Improvements Vin .Printing-Presses, of which the following is aspecication. j

This invention relatesto an improvement in` riage is used which contains the form or block, to which is secured a weighted apronthatlpasses over the. presser-'roller-suem forV inl stance, as shown inthe press described in L et-y ters PatentNo. 7 ,7 S6, dated November 19, 1850.

using them for printing on muslin or similar limber material such material, on entering beand the operation of printing is not a success.l

My invention consists in the combination, with the carriage containing the form or block to be printed from, and with the weighted apron and presser roller, of an additional guide-roller for the apron, said guide-roller beand close above the carriage, so that by its action theV material. to be printed is laid down smooth upon the form or block, and the operation of printing can be carried on without difficulty. n Y

This invention is illustrated in the accompanying drawings, in which Figure 1 repre-V4 sents a perspective view of my press. Fig. 2 is a longitudinal vertical section.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the frame, which is provided with guideways a a for the carriage B. To this frame are firmly vided with guide-slots b b for the j ournal-boxes c of the presser-roller D, and also for the jour-v nal boxes dof a roller,.E, the shaft e of which extends beyond the frame and carries a hand- From the j ournal-boxes d extend arms f into slots formed on-.the ends of knuckles g, which extend from a.- shaft, h, that has its bearings in the bottom ends-of the guide-slots b in the standards O. On one end of vthis shaft is mounted a hand-lever, G, so that by its means 5o secured anapron, H, which extends beneath Y thepresser-roller D-and round an additional roller, I," the` shaft of which is mounted in lugs o2, forming part of the frame A, and which is placed above the carriage B, so that the same,

Vmaterial to be printed, can .be passed beneath saidrolle'r without producing any perceptible .pressure upon the material to be printed. In presses of this class I have found that in From the upperjor outer end of the apron together with its form or block and with the 6o H'extends a rope, j,over a roller, c,secured 65 Ato a yoke, Z, which rises from the frameA,and a weight, K, which is suspended from the rope j, serves to keep the apron taut.

After the material to be printed has been placed smoothly ,upon the form or block in the 7o carriage B the roller E is raised by the handlever G, so as to compress the carriage firmly between it and the presser-roller D, and then `byturning the hand-crank F the carriage is caused to move inward between the two rollers E and D. During this motion the apron H is drawn in so as toV lie upon the material to'be printed,`and by the action of the additional roller I the material to be printed is .kept smoothly down upon the form or block, 8o

so that its surface is printed uniformly as the same passes beneath the presser-roller D.

Y My press is intended particularly for the purpose of printing fiags or other articles of a similar nature, which are made of muslin or other equivalent limp material, and I have Afound that the Y success of the operation depends entirely upon the additional roller I, which prevents the material from puckering.

I do not claim as my invention the combination of the weighted apron with the carriage and the presser-roller, such being old and well known.

What I claim as new, and desire to secure by Letters Patent, is-

In aprintingmachine,the combination, with the apron attached at one end to the horizontal reciprocating carriage and weighted at its other end, and the presser-roller D, for pressing the apron down, of the smoothing-roller I, extending across the apron in front of the presser-roller, and around which the apron is drawn when the carriage is moved for smoothing the apron in advance of the presser-roller, all substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.

JOHN E. GRUMBACH.
